ADMISSIBILITY OF DUPLICATES
A duplicate is admissible to the same extent as an original unless (1) a genuine question is raised as to the authenticity of the original or (2) in the circumstances it would be unfair to admit the duplicate in lieu of the original.
This rule is identical to the federal rule. There is no case law in this State on the admissibility of a duplicate in this context, only on the admissibility of a duplicate as secondary evidence. See Note following Rule 1004.
